Description

INDUSTRIAL APPLICABILITY The present invention purifies and purifies the air taken into a blower such as a fan, which is installed indoors or outdoors and is used to reduce the sensible temperature due to direct airflow and to circulate the air in the room. It is related to an air purifier with a ventilation function used for purifying indoor air by blowing out air as an air flow, reducing the sensible temperature by direct air flow, and circulating air in the room.

Conventionally, in this type of blower, an impeller and a motor are enclosed in a base that serves as a pedestal, and air is circulated so as to be blown horizontally from a ring-shaped blower provided on the upper part of the base to the floor surface. And a household blower that produces an air flow is known (see, for example, Patent Document 1).

Hereinafter, the blower device will be described with reference to FIGS. 7 and 8 .

FIG. 7 shows a front view showing an example of a conventional blower assembly, and FIG. 8 shows a side sectional view of a portion of the blower assembly of FIG. 7 taken along the XX'line. The blower assembly 100 has an annular nozzle 101 that defines a central opening 102. Inside the base 116 of the blower assembly 100, a blower device that generates an air flow through the annular nozzle 101 is arranged. In the blower, the impeller (impeller) 130 is connected to a rotary shaft extending outward from the motor 122 arranged together with the motor housing 126, and the diffuser 132 is positioned downstream of the impeller 130. The motor 122 is connected to an electrical connection and a power source (not shown), and the user can operate the blower assembly 100 by the plurality of selection buttons 120 shown in FIG. 7 .

With the above configuration, the blower assembly 100 operates as follows.

When the user selects a favorite button from the plurality of selection buttons 120 shown in FIG. 7 and the motor 122 is activated, air is sucked into the blower assembly 100 through the air inlet 124. Air flows through the outer casing 118 to the inlet 134 of the impeller 130. The airflow exiting the outlet 136 of the diffuser 132 and the exhaust section of the impeller 130 is divided into two airflows traveling in opposite directions through the internal passage 110.

The air flow is throttled as it enters the mouth 112 and is further throttled at the outlet 144 of the mouth 112. This throttle creates pressure in the annular nozzle 101.

The airflow thus created overcomes the pressure generated by the throttle and exits through outlet 144 as a primary airflow. The primary airflow is focused or focused towards the user by the arrangement of the guide portion 148. The secondary airflow is generated by suction of air from the external environment, particularly the region around the outlet 144 and around the outer edge of the annular nozzle 101. This secondary airflow passes through the central opening 102, where it mixes with the primary airflow to produce a total airflow that is ejected forward from the blower assembly 100.

The air blower according to the present invention has a housing provided with a first suction port and a second suction port for sucking air, a high-pressure air generating portion provided inside the housing and generating high-pressure air, and one surface of the housing. The pillars are provided with a plurality of pillars erected from the above, and the pillars blow out the high-pressure air generated in the high-pressure air generator in the direction perpendicular to the direction in which the pillars are erected to the outside of the housing on the front side portion. It is provided with an outlet that blows out as an air flow, and a plurality of pillars are provided with a gap so that the outlets are flush with each other, and an attracted airflow generated by being attracted to the blown airflow between the adjacent outlets. The attracted airflow region through which air flows is formed, the first suction port is provided at a position not related to the upstream side in the air blowing direction from the air outlet, and the second suction port is on the upstream side in the air blowing direction from the air outlet. It is provided at a position and is characterized in that it is configured to be able to switch between a first airflow control for sucking air from a first suction port and a second airflow control for sucking air from a second suction port.

As a result, the pressure in the attracted airflow region of the attracted airflow generated by being attracted to the blown airflow changes due to the change in the flow rate of the attracted airflow due to the change of the suction port, and the blown airflow affected by the pressure in this attracted airflow region. It has the effect of being able to change the flow of.

First, when the first airflow control is selected, the first suction port is provided at a position not related to the upstream side in the blowing direction from the air outlet, so that the attracted airflow region is the suction airflow flowing to the first suction port. Since it is not affected by the above, the difference between the indoor air pressure in the region outside the outermost pillar and the air pressure in the attracted airflow region is small. Therefore, the airflow blown from each outlet including the airflow blown from the outlet of the outermost pillar goes straight, and the airflow from each outlet does not converge and is blown in a dispersed state. To. On the other hand, when the second airflow control is selected, the second suction port is provided at a position on the upstream side in the air blowing direction from the air outlet, so that the induced airflow region is affected by the suction airflow flowing to the second suction port. Therefore, the air pressure in the attracting airflow region becomes low. For this reason, a pressure difference occurs between the indoor air pressure in the region outside the outermost pillar and the air pressure in the attracting airflow region, and the airflow from the outlet of the outermost pillar is the attracting airflow having a pressure lower than the indoor air pressure. Deflection toward the region. Each pillar inside the outermost pillar is also deflected toward the attracting airflow region on the central region side. As a result, the airflow blown out from the outlet of each pillar converges toward the central region. Therefore, in the airflow by the first airflow control, each blown airflow does not converge as compared with the airflow by the second airflow control, so that the airflow range is wide, the wind speed is slow, and the airflow becomes uniform. Further, in the blowing by the second airflow control, each blowing airflow converges as compared with the blowing by the first airflow control, so that the blowing range is narrow, the wind speed is fast, and the blowing distance is long.

As a result, when the first airflow control is selected, a low wind speed airflow with a wider airflow range is created than when the second airflow control is selected, so that a large number of users can obtain a cool feeling. become. On the other hand, when the second airflow control is selected, a high wind speed airflow with a narrower airflow range is created than when the first airflow control is selected, so that a small number of users can obtain a strong cool feeling. And the efficiency of air circulation can be improved.

Further, the control unit of the blower device is characterized by including a third airflow control for sucking air from both the first suction port and the second suction port.

This makes it possible to select a third airflow control in which the air pressure in the attracted airflow region is lower than that of the first airflow control and higher than that of the second airflow control.

As a result, it is possible to create a third airflow control airflow having a faster wind speed than the first airflow control and a wider airflow range than the second airflow control.

Further, the blower device is characterized in that the intake air from each suction port is switched by a shielding plate. This makes it possible to select between the first airflow control and the second airflow control with a simple flat plate. As a result, it is possible to reduce the assembly man-hours and the cost by reducing the number of parts.

Further, the blower is characterized in that a shielding plate is provided inside the housing. This makes it possible to select between the first airflow control and the second airflow control without having to operate the parts constituting the appearance of the blower. As a result, it becomes possible to maintain the high design of the blower and have the second airflow control and the first airflow control.

Further, the blower is characterized in that the shielding plate is provided on the outside of the housing. This makes it possible to select between the first airflow control and the second airflow control by operating the shielding plate having visibility. As a result, the user can recognize the setting status of the blower mode from the appearance of the blower device.

Further, the air purifier with a blower function is an air purifier with a blower function, characterized in that the first suction port or the second suction port of the blower is provided with an air purification filter. As a result, the air taken in from the suction port is purified by the air purification filter and blown out from the outlet, so that the purified air can be provided to the user.

A small number of 5 are formed. Hereinafter, the region where the attracting air passage is formed is referred to as an attracting airflow region 10.

As shown in FIG. 3, the first shielding plate 12 can be inserted into the first shielding plate insertion port 13, and the second shielding plate 11 is inserted into the second shielding plate insertion port 14. It is possible to do. The state of the first airflow control and the state of the second airflow control can be switched depending on whether or not each shielding plate is inserted.

On the other hand, as shown in FIGS. 1B and 3B, the first shielding plate 12 is inserted into the first shielding plate insertion port 13, and the second shielding plate 11 is inserted through the second shielding plate insertion port 14. The second airflow control state is the state in which the first suction port 3 is closed and the second suction port 4 is opened.

Further, as shown in FIG. 3, in the case of the first airflow control, the second shielding plate 11 that closes the second suction port 4 is inserted into the blower device 1, and in the case of the second airflow control, the second airflow control is performed. The first shielding plate 12 that closes the first suction port 3 is inserted into the air blower 1. The first shielding plate 12 and the second shielding plate 11 have a first shielding plate insertion port 13 and a second shielding plate insertion port 14 on the side surface 15 of the blower 1, respectively, so that they can be manually attached and detached.

FIG. 4 shows a cross-sectional view showing the internal shape of the blower 1 in the cross section AA'in FIG. 2 and a schematic view of the air flow. Note that FIG. 4A is a state of the first airflow control of the blower device 1, and FIG. 4B is a state of the second airflow control of the blower device 1.

As shown in FIG. 4, the inside of the pillar 6 is provided with a duct 16 for guiding high-pressure air to the outlet 8. The number of ducts 16 is the same as that of the pillars 6. A chamber space 17 for distributing high-pressure air to each pillar 6 is provided between the high-pressure air generating unit 5 and the plurality of ducts 16.

According to such a configuration, as shown in FIG. 4, a motor (not shown) constituting the high-pressure air generating unit 5 is driven and the impeller 23 is rotated, so that the internal flow 18 is shown. The indoor air is taken into the inside of the blower device 1 (housing 2) as a suction airflow 19 from the first suction port 3 or the second suction port 4, passes through the impeller 23, and reaches the chamber space 17. The high-pressure air formed by passing through the impeller 23 is diverted into six ducts 16 in the chamber space 17, passes through each duct 16, and is a pillar at the wind direction adjusting rib 20 provided near the air outlet 8. 6 The wind blown in the upright direction is deflected and blown out from the outlet 8 to form the blown airflow 21.

As shown in FIG. 4A, in the state of the first airflow control, the suction airflow 19 is taken in from the front surface of the housing 2. On the other hand, as shown in FIG. 4B, in the state of the second airflow control, the suction airflow 19 is taken in from the upper surface on the rear side of the housing 2.

FIG. 5 shows a cross-sectional view showing the internal shape of the blower 1 in the cross section of BB'in FIG. 2 and a schematic view of the flow. As shown in FIG. 5, the cross-sectional shape of the pillar 6 is a rectangular shape, but it may be any other shape such as an ellipse as long as it extends in the blowing direction.

Due to the viscosity of air, another airflow is generated by attracting the stationary air around the airflow to the airflow flowing at a constant wind speed. Also in this configuration, another airflow generated by being attracted to the airflow blown out from the air outlet is generated, and these two types of airflow are combined and blown.

In the first embodiment, as shown in FIG. 5, the air in the adjacent attracted airflow region 10 by being attracted to the blown airflow 21 blown out from the outlet 8 (in the outermost pillar 6, the adjacent attracted airflow). The air in the airflow region 10 and the air outside the outermost pillar 6) are attracted, and the attracted airflow 22 (the attracted airflow outside the outermost pillar 6 is not shown) is generated by the blown airflow 21. The blown airflow 21 and the attracted airflow 22 merge downstream of the outlet 8 of the blower device 1, and it becomes possible to create a substantially uniform airflow over a wide area.

Details will be described later, but at this time, the position of the intake air that takes in the indoor air inside the blower 1 (housing 2) is the air pressure in the induced airflow region 10 depending on whether the first suction port 3 or the second suction port 4 is used. Changes. The flow of the blown airflow 21 changes due to the influence of the air pressure in the attracted airflow region 10. As a result, the wind direction of the merging airflow in which the blowing airflow 21 and the attracting airflow 22 merge changes.

The flow of each airflow in each of the first airflow control and the second airflow control of the blower 1 will be described below.

FIG. 6 shows a cross-sectional view showing the internal shape of the blower 1 in the cross section AA'in FIG. 2 and a schematic view of the air flow.

When the first airflow control is selected, air is taken into the inside of the housing 2 from the first suction port 3. The first suction port 3 is provided on the front surface of the housing 2, and the position of the first suction port 3 is a position not related to the upstream side in the air blowing direction from the air outlet 8. The position not related to the upstream side in the blowing direction from the air outlet 8 is the position on the downstream side of the air outlet 8 in the air flow 21 and the induced air flow 22. In this case, as shown in FIGS. 5A and 6A, the attracting airflow region 10 is not affected by the suction airflow 19 flowing through the first suction port 3, so that the region outside the outermost pillar 6 is not affected. The difference between the indoor air pressure and the air pressure in the attracting airflow region 10 is small. Therefore, as shown in FIG. 5A, the airflow 21 blown from each of the outlets 8 including the airflow blown from the outlet 8 of the outermost pillar 6 travels straight, and each of them travels straight. The airflow 21 from the outlet 8 of the above is blown in a dispersed state without converging.

On the other hand, when the second airflow control is selected, air is taken into the inside of the housing 2 from the second suction port 4. The second suction port 4 is provided on the upper surface on the rear side of the housing 2, and the position of the second suction port 4 is a position on the upstream side in the air blowing direction from the air outlet 8. In this case, as shown in FIGS. 5B and 6B, the attracting airflow region 10 is affected by the suction airflow 19 flowing through the second suction port 4, so that the air pressure in the attracting airflow region 10 becomes low. Therefore, a pressure difference occurs between the indoor air pressure in the region outside the outermost pillar 6 and the air pressure in the attracting airflow region 10, and the airflow 21 from the outlet 8 of the outermost pillar 6 is larger than the indoor air pressure. It deflects to the attracted airflow region 10 side of low atmospheric pressure. Each pillar 6 inside the outermost pillar 6 is also deflected toward the attracting airflow region side on the central region side. As a result, the blown airflow blown out from the outlet of each pillar 6 converges to the central region side.

Therefore, in the airflow by the first airflow control, the respective blown airflows 21 do not converge as compared with the airflow by the second airflow control, so that the airflow range is wide, the wind speed is slow, and the airflow becomes uniform. Further, in the blowing by the second airflow control, the blowing airflows 21 are converged as compared with the blowing by the first airflow control, so that the blowing range is narrow, the wind speed is fast, and the blowing distance is long.

As a result, when the first airflow control is selected, a low wind speed airflow with a wider airflow range is created than when the second airflow control is selected, so that a large number of users can obtain a cool feeling. become. On the other hand, when the second airflow control is selected, a high wind speed airflow with a narrower airflow range is created than when the first airflow control is selected, so that a small number of users can obtain a strong cool feeling. And the efficiency of air circulation can be improved.

In the blower device 1 of the first embodiment, it is possible to easily switch between the first airflow control state and the second airflow control state only by changing the position of air taken into the inside of the housing 2. be. Further, the user of the blower device 1 can appropriately change the range and the wind speed of the wind.

The present disclosure has been described above based on the embodiments. It will be appreciated by those skilled in the art that these embodiments are exemplary and that various variations of each of these components and combinations of processing processes are possible and that such modifications are also within the scope of the present disclosure. By the way.

In the first embodiment, since the high-pressure air generating unit 5 is contained in the housing 2, the structure is such that the user cannot contact from the outside, and it is possible to eliminate the anxiety caused by the contact. The high-pressure air generating unit 5 may be installed outside the housing 2.

Further, in the first embodiment, as shown in FIG. 4, a wind direction adjusting rib 20 for deflecting the wind along the upright direction of the pillar 6 is provided in the vicinity of the air outlet 8 in the pillar 6. As a result, the high-pressure air sent out from the high-pressure air generation unit 5 is deflected from the upright direction of the pillar 6 and blown from the outlet 8. However, it is not necessary to provide such a wind direction adjusting rib 20.

Further, in the first embodiment, each of the first shielding plate 12 and the second shielding plate 11 can be manually attached to and detached from the inside of the blower device 1. As a result, since the complicated structure of the blower 1 and the remote controller for operating the first shield plate 12 and the second shield plate 11 in the blower 1 are not required, it is possible to reduce the assembly man-hours and the cost. Become. Further, since the components of the blower device 1 having visibility are not operated, it is possible to have the second airflow control and the first airflow control while maintaining the appearance of the blower device 1.

However, by adopting a mechanism in which the first shielding plate 12 and the second shielding plate 11 are operated by a stepping motor or the like, the user can automatically operate each shielding plate by using a remote controller for operating the stepping motor or the like. It may be made removable. This makes it possible to appropriately change the wind range and wind speed without forcing the user to labor and time.

Further, in the first embodiment, it is clarified that the place where the indoor air is taken into the air blower 1 is either the first suction port 3 or the second suction port 4, but the first suction port 3 and the second suction port 3 are specified. Both of the suction ports 4 may be used as suction ports. As a result, the third airflow control in which the pressure in the attracted airflow region 10 is lower than that in the first airflow control and higher than that in the second airflow control is selected. As a result, it is possible to have a third airflow control having a higher wind speed than the first airflow control and a larger wind receiving range than the second airflow control, and the wind range and the wind speed can be changed more appropriately.

Further, in the first embodiment, all the pillars 6 are provided in parallel with the blowing direction, but the direction and the number of pillars 6 are not particularly limited. However, the wide-angle lens may be provided so that the air blowing direction is separated from the pillar 6 in the central portion toward the pillar 6 provided on the outside from the center of the housing 2. As a result, the phenomenon that the airflow gathers in the central portion of the blower device 1 can be suppressed up to a certain distance from the blower device 1, and the range of the wind can be widened. However, since the degree of strength of this phenomenon largely depends on the width of the gap 9 sandwiched between the pillars 6, no significant effect can be expected.

Further, in the first embodiment, the number of pillars 6 is 6, the width of the blower 1 is 620 mm, the width of the pillars 6 is 45 mm, and the length of the gap 9 is 100 mm, but these design values are particularly limited. There is no. However, the user can appropriately change the width of the blower 1 and the number of pillars 6 depending on the space and design.

Further, in the first embodiment, a purification filter may be provided for at least one of the first suction port 3 and the second suction port 4 of the blower device 1. As a result, by purifying the air taken in from each suction port with a filter, it is possible to suppress the adhesion of dirt to the high-pressure air generating portion 5, and it is possible to provide the blower device 1 in which the blower performance is less likely to deteriorate.

Further, in the first embodiment, an air purification filter may be provided for at least one of the first suction port 3 and the second suction port 4 of the blower device 1. This makes it possible to blow purified air, and the blower 1 can be provided as an air purifier with a blower function.

The blower device and the air purifier with a blower function according to the present invention are useful as a blower device capable of appropriately changing the range and speed of the wind by the user.
